On my Droid Maxx, there seems to be some problems with the headphone jacks. If I am listening to music and the headphone bends or moves in anyway, it turns the music off and I have to take out the headphone and put it back in to get it to work again. It is very sensitive, so sometimes it can happen every 10 seconds especially when I am working out. The sound is fine when they do work. I know its not the headphones as I have used multiple headphones )actually replaced a pair thinking they were broken) and it has not fixed the issue.
